True and false lithium batteries, will you tell?

The service life of lithium batteries is limited. I believe this is undeniable. Take the mobile phone batteries that you use. Generally speaking, this means you need to replace a new battery. The problem is now. The quality of products in the lithium battery market is mixed, and there are many counterfeit goods. How to distinguish it? Today I will tell you a few tricks:

1. Compare the size of the battery capacity. The general nickel-cadmium battery is 500mAh or 600mAh, and the hydrogen-nickel battery is only 800-900mAh. The capacity of the lithium-ion mobile phone battery is generally between 1300-1400mAh, so the time for the lithium battery to be fully charged is about the hydrogen-nickel battery. 1.5 times, about 3.0 times that of cadmium-nickel batteries. If you find that the working hours of the lithium-ion mobile phone battery block you purchased are not advertised or as long as specified in the manual, it may be counterfeit.

2. Look at the plastic surface and plastic material. Authentic battery wear surface is uniform, using PC material, no brittle phenomenon; counterfeit battery without anti-wear surface or too rough, using recycled material, easy to crack.

3. All genuine mobile phone batteries should be neat in appearance, without excessive burrs, the outer surface has a certain roughness and felt comfortable, the inner surface is smooth, and fine vertical scratches can be seen under the light. The battery electrode and the mobile phone battery have the same width. The corresponding position under the battery electrode is marked with [+], [-]. The isolation material of the battery charging electrode is the same as the outer casing material, but it is not integrated.

4. For the original battery, its battery surface color texture is clear, uniform, clean, no obvious scratches and damage; battery mark should be printed with battery type, type, rated capacity, standard voltage, positive and negative signs, manufacturer name . The hand should be smooth and non-blocking, suitable for tightness, good fit with the hand, reliable lock; the metal piece has no obvious scratches and black and green. If the cell phone battery we purchased does not match the above phenomenon, it can be preliminarily determined to be a fake.

5. At present, many mobile phone manufacturers have also made efforts to improve the level of craftsmanship to improve the difficulty of fraud in mobile phones and their accessories, thereby further curbing the phenomenon of counterfeit goods. Generally, regular mobile phone products and their accessories must be consistent in appearance. Therefore, if we put the purchased mobile phone battery, should we carefully compare the fuselage and the battery bottom case color, if the color is dark and consistent, it is the original battery. Otherwise, the battery itself is dull and dull, and it may be a fake battery.

6. Observe the abnormal situation of charging. Generally, the internal mobile phone battery should have an overcurrent protector. In the case of excessive current caused by external short circuit, the circuit is automatically cut off to avoid burning or damage the mobile phone. The lithium ion battery also has an overcurrent protection circuit. Standardize the electrical appliance. When the AC current is too large, the power will be automatically cut off, resulting in no charge. In normal battery condition, it can automatically return to the conduction state. If, during the charging process, we find that the battery is seriously hot or smoke, or even explode, the battery is definitely faked.
